THE WATSONS STUDY THE ADVERBS OF FREQUENCY

Time
Today, The Watsons and The Grandma have continued studying English with Google Applications. 

The Grandma has explained them how to create a meet with Google Meet and they have been talking about the importance of Google Calendar. After this, they have been practising the Adverbs of Frequency.

Time is something essential in our lives and it is important to know how to organise it to work and enjoy.

Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future.

It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.

Time is often referred to as a fourth dimension, along with three spatial dimensions.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.

Time in physics is operationally defined as what a clock reads. Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second. Time is used to define other quantities -such as velocity- so defining time in terms of such quantities would result in circularity of definition.

An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event, such as the passage of a free-swinging pendulum, constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. To describe observations of an event, a location -position in space- and time are typically noted.

Time
The operational definition of time does not address what the fundamental nature of it is.

It does not address why events can happen forward and backwards in space, whereas events only happen in the forward progress of time.

Investigations into the relationship between space and time led physicists to define the spacetime continuum.

General Relativity is the primary framework for understanding how spacetime works. Through advances in both theoretical and experimental investigations of space-time, it has been shown that time can be distorted, particularly at the edges of black holes.

Temporal measurement has occupied scientists and technologists, and was a prime motivation in navigation and astronomy. Periodic events and periodic motion have long served as standards for units of time. Examples include the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum, and the beat of a heart.

Currently, the international unit of time, the second, is defined by measuring the electronic transition frequency of caesium atoms. Time is also of significant social importance, having economic value, time is money, as well as personal value, due to an awareness of the limited time in each day and in human life spans.

Generally speaking, methods of temporal measurement, or chronometry, take two distinct forms: the calendar, a mathematical tool for organising intervals of time, and the clock, a physical mechanism that counts the passage of time. In day-to-day life, the clock is consulted for periods less than a day whereas the calendar is consulted for periods longer than a day.

Increasingly, personal electronic devices display both calendars and clocks simultaneously. The number, as on a clock dial or calendar, that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epoch -a central reference point.

Artifacts from the Paleolithic suggest that the moon was used to reckon time as early as 6,000 years ago.

Time
Lunar calendars were among the first to appear, with years of either 12 or 13 lunar months, either 354 or 384 days. Without intercalation to add days or months to some years, seasons quickly drift in a calendar based solely on twelve lunar months.

Lunisolar calendars have a thirteenth month added to some years to make up for the difference between a full year, now known to be about 365.24 days, and a year of just twelve lunar months. The numbers twelve and thirteen came to feature prominently in many cultures, at least partly due to this relationship of months to years.

Other early forms of calendars originated in Mesoamerica, particularly in ancient Mayan civilization. These calendars were religiously and astronomically based, with 18 months in a year and 20 days in a month, plus five epagomenal days at the end of the year.

The reforms of Julius Caesar in 45 BC put the Roman world on a solar calendar. This Julian calendar was faulty in that its intercalation still allowed the astronomical solstices and equinoxes to advance against it by about 11 minutes per year.

Pope Gregory XIII introduced a correction in 1582; the Gregorian calendar was only slowly adopted by different nations over a period of centuries, but it is now by far the most commonly used calendar around the world.

During the French Revolution, a new clock and calendar were invented in an attempt to de-Christianize time and create a more rational system in order to replace the Gregorian calendar. The French Republican Calendar's days consisted of ten hours of a hundred minutes of a hundred seconds, which marked a deviation from the base 12, duodecimal, system used in many other devices by many cultures. The system was abolished in 1806.

Another form of time measurement consists of studying the past. Events in the past can be ordered in a sequence, creating a chronology, and can be put into chronological groups, periodization.

One of the most important systems of periodization is the geologic time scale, which is a system of periodizing the events that shaped the Earth and its life. Chronology, periodization, and interpretation of the past are together known as the study of history.
